5 Flute Variable Index End Mills for Hard Materials

These 5 flute end mills are recommended for milling
very hard materials over 50Hrc. They also have a
38° Helix and Variable Index like all our HighPerformance End Mills. One critical feature of this
end mill is the very thick core for added rigidity in
tough materials. The end mills also have an Eccentric
Relief with a Heal Grind. We recommend a lighter
chip load with this geometry but this added rigidity from the thick core will allow you to run much faster than
“regular” geometry 5 flute tools.
We offer this 5 flute end mill either with a FerroCon coating for hardened steels and tools steels or InoxoCon
for Nickel Alloys and Super Alloys. This tool’s geometry aided by the Nano-Coating offers excellent performance in
harder materials and is great in high speed milling operations.
* For CHAMFERED end mills enter a C as the first character in the part number. For example a 1/2” 4 flute uncoated
end mill will have a part number or C-FT4-500. Standard Chamfer is 5% of Diameter. Any size can be requested.
* For Radius end mills enter an R as the first character in the part number. For example a 1/2” 4 flute uncoated end
mill will have a part number or R-FT4-500. Standard Radius is 5% of Diameter. Any size can be requested.
* F at the end means FerroCon Coated, I means InoxoCon Coated.
